3 Claims.

My invention relates to dough sheeting devices, and more particularly to a dough sheeting device for transversely sheeting dough.

It is a particular purpose of my invention to provide means for sheeting dough, which involves means for first sheeting the dough in one direction and then sheeting the dough transversely of the first sheeting action.

In dough molding machines, such as loaf molding machines, pieces of dough are first sheeted and then curled up on themselves to form the loaf, and after the loaf has been formed it is usually deposited ina pan byv automatic panning means. In the ordinary molding machine the piece of dough, which has a thin dry skin coat thereon, and a moist interior, is passed between rollers in only one direction and as a result the moist dough on the inside of the dough piece'is pressed to the surface thereof except at the forward end edge thereof. The dry surfaced forward end edge will be in the center of theloaf and this dryness causes the development of holes and white spots in the baked load.

It is a purpose of my invention to provide a sheetingmeans for dough pieces, which serves to squeeze the moisture in the dough piece to the surface thereof to provide a moist surface at the rear or sealing end edge of the piece when it is curled or rolled up and yet not have the forward end edge dry on its surface either. This is accomplished by passing the dough piece after it has been sheeted in one direction through rollers that sheet it ina direction transverse to the first direction of sheeting. 7

.It is a further purpose of my invention to provide such a sheeting means for transversely sheeting the piece of dough between the first sheeting means and the curling means and to provide a sheeting means at this location that will properly locate and size the piece ofdough so that it will be deposited on the conveyor that feedsthe same into the curling mechanism in a proper position that it will align with the pan to which the particular dough piece is fed on the panning device, which is usually although not necessarily, a part of the molding machine.

,A molding machine, such as that to which my invention is adapted to be applied, usually comprises a curling device including a pressure board to whichthe conveyor feeds the sheeted pieces of dough. It is necessary that the pieces of dough beexactly in the right position relative to the pressure board as well as the panning device, and

my improved dough sheeting means provide for the proper positioning of the dough piece of proper width so that it will becurled and formed into a loaf and be fed to a pan in such a way that the pan will receive it without any of the loaf overlapping any of the end portions of the pan.

Other objects and advantages of my invention will appear as the description of the drawings proceeds; I desire to have it understood, however, that I do not intend to limit myself to the particular details shown or described, except as defined in the claims.

In the drawings:

Fig. 1 is a view partly in elevation and partly in longitudinal section through a loaf molding.

and panning machine, showing my invention applied thereto.

Fig. 2 is a section taken on the line 2-2 of Fig. 1, and r Fig. 3 is a section taken on the line 3-3 of Fig. 1.

Referring in detailto the drawings, the molding machine that incorporates my dough sheeting means has a sheeting device to which pieces of dough are fed, comprising the sheeting rollers 43,. 5, 6 and l, the rollers 4 and 5 being plain cylin drical rollers and the rollers 6 and 1 being flanged.

Said rollers are mounted in a suitable housing over sprockets fixed on shafts carrying the rollers 4 and 5. The rollers 6 and l are driven by means of the rollers 4 and 5 being free to roll on their shafts.

A conveyor comprising the belt [4 receives the sheeted pieces of dough 9, saidbelt moving in the direction indicated by the arrow in Fig. 2 to carry the sheeted pieces of dough over the large roller [5, pieces of sheeted dough 9 passing over the roller I5 on the conveyor belt so as to be discharged and turned over so that theside that was bottommost on the belt 14 will be uppermost by the time the dough reaches the position shown at the right of the roller 15 in Fig. 2. The above described parts, which are common in bread molding machines of the character to which my invention is applied, are mounted on a suitable frame I6 and a frame I1 is provided that extends in a direction that is transverse to the direction of travel of the conveyor M or transverse to the direction in which said piece of dough 9 has been rolled out by the sheeting rollers ll, 5, 6 and l.

3 Said frame ii is provided with a plurality of conveyors comprising the belt conveyor l8, which operates in the direction indicated by the arrow in Fig. 1, operating over the rollers 19 and 20, said roller 28 being driven by means of a sprocket chain 2 I, which is driven from a motor 22 that is mounted on the frame it. Said motor 22 drives 'a sprocket chain 23 that operates over a sprocket 24, which is mounted on a shaft that also has a sprocket thereon that drives the sprocket chain 25, which in turn drives a shaft on which a sprocket is fixed that drives the chain 2|, the sprocket chains being driven in the direction indicated by the arrows in Fig. 1. The conveyor i8 receives the pieces of dough 9 that have been sheeted and carries-them away from the sheeting mechanism that has produced the sheeted piece of dough e in a direction trans" verse to that in which th sheeting action has taken place, or in which the pieces of dough 9 have been rolled out into a sheeted form. The conveyor 14 operates over a roller 26 that is driven by the sprocket chain ii, being fixed on theshaft carrying the sprocket ii.

The pieces of dough that are on the conveyor belt i8 traveling toward the upper end thereof Where the same passes around the roller 28 are in such position after having turned over and having been received by said belt it that the edge 21 of said pieces, which was rearinost after having been sheeted by the rollers A and S, and and I, is substantially parallel to one of the side edges of the conveyor belt 18, as will be obvious from Fig. 2. There is nothing, however, to assure the specific location of the pieces of dough 9 on the belt l8 because the same drop freely from the belt M, where it passes over the roll i5, onto the belt It. In order to make a loaf or loaflike member, such as a loaf of bread, out of the piece of dough, it has to be rolled up or curled up on itself. For this purpose curling mechanism is provided, which comprises a flexible chain mesh member 28 that depends from a bracket 29 on the extension 30 of the frame 11, and which engages a conveyor belt 3|, which moves in the direction indicated by the arrow in Fig. 1, being mounted to pass over rollers 32 and 33, said roller 32 bein a driven roller driven by a sprocket over which the chain 25 operates. The flexible chain mesh member 28 dragging on the conveyor belt to the next turn and thus hold the curled-up piece together in loaf-like form.

Suitable adjusting means 3? are provided for the pressure board and this pressure board may be of any desired material or character, ordina'rily having a tapered forward end 33 to direct the pieces of dough under the pressure board. The pieces of dough that are being carried along by the conveyor belt 3!, after being engaged by the flexible member 28 and the pressure board 36, usually pass to a panning device, the panning device being of a character to place the pans 39 in a suitable position to receive the formed loaves 35.

The panning device comprises a pan feeding means consisting of a plurality of conveyor rollers 40, over which the pans are fed in any suitable manner to the conveyor EH, which usu- 4 ally comprises a pair of spaced belts driven in the direction indicated by the arrow in Fig. 1 by means of the chain 23 operating over the sprocket 2 The details of construction of the panning device are of no particular importance to my invention, except that the panning device is actuated by means of the loaves 35 that are passing along the conveyor 31 by engagement with a suitable actuating member 42, which releases suitable holding mechanism 43 extending between said belts to permit a pan 39 to move into proper position to receive a molded loaf, and

vwhich is provided with suitable means, such as the stiff flexible member 44, for straightening the dough iece on the belt so that it extends par allel to the pan 39 when it drops into the same, said member i i being held in loaf engaging position by a spring 4 3.

As the'rolled-up pieces of dough 35 forming the loaves are of a length closely approaching the length of the ans, it is highly important that the pieces of dough that have been curled up are in the right position on the conveyor belt 3i transversely thereof that the same will properly align with the pans on the conveyor 42. The conveyor 3i operates in a straight line over the driven roller 65 and the idler roller 46, and any suitable means may be provided for centering the ans properly on the conveyor 4i, this being common to apparatus of this character, not being part of my invention.

It is also important that the pieces of dough that are curled by means of the member 28 are fed in proper alignment with the pressure board and that the same engage the pressure board exactly at the same location transversely of the board so that said pressure board will act over the whole length of the curled-up pieces of dough and so that the pieces of dough that have been rolled up on themselves and formed into a loaf by the combined action of the flexible member 28 and the pressure board 36 will b in the proper position on the conveyor '3! transversely of said conveyor belt to feed into the pans 39 accurately and revent any overlap of the loaf beyond either end of the pan, which would make it necessary to straighten out the loaf in the pan in order that a perfect loaf of bread will be formed in the pan during the proofing operation.

My improved transverse sheeting means that forms a part of the machine illustrated in the drawings and is the'principal feature of my iiivention, is provided to not only transversely sheet the dough piece, but to definitely locate the piece of dough relative to the flexible means 28, the pressure board '36 and the panning device. Said sheeting means comprises a driven plain cylindrical roller 41, which is mounted in suitable bearings daonthe side members 49 of the extension 30 of the frame H, a sprocket 50 being fixed on the shaft 51 extending from and rotating with the roller 41, over which the sprocket chain 2| Operates to drive said roller 41 in a clockwise (ii rection as viewed in Fig. 1. The'sheeting roller 41 has a sheeting roller 52 cooperating therewith, which is rovided with marginal flanges 53 between which the roller 4! fits as shown in Fig. 3. The roller 41 will receive the pieces of dough '9 that have passed onto the conveyor 18 and will convey said pieces of dough in the general direction in which they have been traveling on the v y r l8 and into engagement with the roller '52, the rollers 41 and 52 cooperating to transversely sheet the dough or roll it out in a direction transverse to the direction in which it was sheeted or rolled out by the sheeting mechanism compris ing the rollers 4 and 6, and 5 and I.

When" the pieces of dough were sheeted by said sheeting means comprising the roller 4, 6, 5 and I the cells formed in proofing the rounded pieces of dough are broken down and the moist dough on the inside of the dough piece was squeezed outwardly to the surface thereof except at the .forward end edge 54 thereof. The pieceof dough 9 accordingly, when it is on the conveyor l8, has one edge 21 that is located substantially parallel to one side edge of the conveyor I8 that will be moist on its surface and a side edge 54 thereof that is substantially parallel to the side edge of the conveyor belt [8 that is dry on its surface. However, after'the rollers 52 and 41 are engaged by said piece of dough, the moist dough .on the inside of the piece will be squeezed outwardly at bothside edges 2! and 54 to the surface and as a result there will be no dry surface remaining on said dough piece at any of the side or end edges thereof. As the moist surfaced end edge 55 is the closing edge when the dough piece has been rolled up as illustrated at in Fig. 1, the pressure board 36 will readily seal the exposed edge 55 of the rolled up piece of dough 35 to the next adjacent layer of the curled up piece. Furthermore, due to the fact that the piece of dough has been rolled first in a manner to cause the moist interior dough in a the piece to travel in one direction, and then has been sheeted or rolled in a direction transversely thereto to cause the moist interior dough in the piece to travel in a direction transversely thereto, the entire dough piece will be moist surfaced on both faces and all edges. The loaf that results will have no large holes develop therein during the proofing operation and will be of a much finer more uniform texture than would otherwise be the case. Also there will be no extremely dry portion in the center of the loaf that would cause white lumps or spots in the loaf of bread which did not properly rise durin the proofing operation.

Due to the provision of the flanges 53 on the roller 52 the cooperating action of the rollers 41 and 52 is such that the pieces of dough will be re-shaped when they are transversely sheeted by said rollers so that the side edges of said pieces will lie at the flanges 53 and the pieces of dough will be of the exact width of the length of roller lying between said flanges, and when the same leave the curling mechanism and pass to the conveyor belt 3| these pieces of dough will be exactly located relative to the conveyor belt so that their side edges will be spaced a definite distance from the side edges of the conveyor belt 3| and will maintain this position a the dough pieces are curled up on themselves by the combined action of the flexible member 28 and the pressure board 36 and pass to the pans 39 in such a manner as to be definitely located relative to said pans transversely of the conveyor belt 3 l.

The pieces of dough having beensheeted by the rollers 4, 6, 5 and 1, previously, the action of the rollers 41 and 52 is principally a re-shaping action and the squeezing action of the rollers 4'! and 52 is not nearly as great as that of the rollers 4, 6, 5 and I, because the rollers d, 6, 5 and 1 have converted the piece of dough from the usual rounded piece that is fed in any suitable manner between the rollers 5 and 6 to a flattened or sheeted piece, whereas when the pieces 9 travel on the conveyor belt l8 to the rollers 41 and 52 these have been flattened or sheeted and only have to be re-shaped slightly to properly locate the same relative to the molding and panning mechanism.

' It is necessary that adjusting means be provided for adjusting the spacing of the rollers 52 and 41 so that said rollers will exert exactly the proper sheeting action onthe pieces of dough to obtain the uniform width thereof that is desired, determinedby the flanges 53. Accordingly the roller 52 is mounted for adjustment relative to the roller 41 by any suitable means, such as that illustrated in Fig. 3 of the drawings. Said roller has shaft portions 56 extending therefrom, which are mounted in suitable bearings 51 in the adjustable bearing brackets 58, which are suitably mounted in slideways 59 in the side members 49 of the frame extension 39, said adjustable members 58 having internally screw-threaded por tions fill that have an adjusting screw 6| engaged therewith. One of the adjusting screws 6| has an extension 62 that is rotatably mounted in the transverse member 63 and has a hand wheel 64 thereon for rotating the same. A sprocket 65 is also provided on said member'fil and a sprocket 66 is provided on the other member 5 l, a sprocket chain 6'! operating over said sprockets 66 and 55 so as to adjust the two adjusting members 6| uniformly upon rotation of the hand wheel 64.
